| A | B |
|---|
| Arachnoid Membrane | Second or middle layer of the meninges |
| Axon | Extends away from the cell body and conducts impulses away from the nerve cell |
| Brainstem | Made up of the midbrain, pons and medulla oblongata. |
| Central Nervous System | Consists of the brain and spinal cord protected by the meinges and cerebrospinal fluid |
| CSF | Cerebrospinal fluid |
| Convolutions | Gyri; the elevated portions of the cerebrum |
| Cranial nerves | There are 12 pairs of these orginating in the brainstem. They control the activities of the face and head. |
| Dendrite | Root like structures that receive impulses and conduct them to the cell body. |
| Dura Mater | Outside layer of the meninges |
| Frontal Lobe | Part of the brain that controls motor function |
| Hypothalamus | Controls vital body functions (heart rate, BP, respiratory rate, digestive tract activity, emotional responses/behavior. Regulates: body temperature, hunger sensations, water balance & thirst, sleep and endocrine activity |
| Medulla Oblongata | The most vital part of the brain, controls basic life functions including muscles of respiration, heart rate, and blood pressure. |
| Meninges | Three layers of connective tissue membrane that enclose the brain and spinal cord. |
| Myelin Sheath | Fatty tissue that surrounds and protects the axon of a nerve cell of the brain and spinal cord. |
| Occipital Lobe | Part of brain that controls eyesight |
| Parietal Lobe | Part of the brain that receives and interprets nerve impulses from the sensory receptors |
| Peripheral Nervous System | PNS |
| Pia Mater | Layer of the meninges that is closest to the brain and spinal cord containing blood vessels |
| Plexus | A large network of nerves |
| Pons | Bridge tissue connecting two parts of an organ. |
| Temporal Lobe | Part of brain that controls the senses of hearing and smell. |
| Thalamus | Monitors sensory stimuli |
| afferent neurons | carry impulses to the brain and spinal cord from the skin and sense organs. |
| Alzheimer's | Progressive memory loss |
| Aneurysm | Widening of a blood vessel |
| Autonomic Nervous System | Nerves that regulate involuntary actions like heartbeat and gland secretions |
| Bell's palsy | Paralysis of facial nerve causing drooping of face |
| Brain | Is a large mass of neurons located in the cranium (skull) |
| Cerebellum | Coordinates motor activities and aids in maintaining balance |
| Cerebrum | Center of control for: voluntary body movements; 5 senses and memory |
| Coma | State of unconsciousness |
| Dementia | Mental decline and deterioration |
| dendrites | branched process of a neuron that receives impulses and carries them to the cell body |
| Dysphasia | Impairment of speech |
| efferent neurons | carry impulses away from the brain and spinal cord to the muscles and glands |
| Gait | Manner of walking |
| ganglion | knot-like mass of nerve tissue located outside the brain and spinal cord |
| Hemiplegia | Paralysis of half the body |
| Impulses | Neurons are used for the transmission of |
| Medulla | Involuntary activities like breathing and heartbeat |
| Meninges | Connective tissue surround the brain/spinal cord |
| Motor neuron | Transmit impulses from the brain and spinal cord to effectors (muscle or gland) |
| Nerve | is a group or bundle of fibers located outside the central nervous system that connect the brain and spinal cord with various parts of the body |
| Neurons | The nervous system is made up of nerve cells called |
| peripheral nervous system | provides a complete network of motor and sensory nerve fibers connecting the central nervous system to the rest of the body |
| Quadriplegia | Paralysis of all four limbs |
| Sensory neuron | Transmit impulses from the sense organs (receptors) to the spinal cord |
| Somatic Nervous System | Consist of nerves that regulate voluntary muscles of the skeleton |
| Stroke | A disorder in which the brain is damaged as a result of cerebral hemorrhage (a broken vessel in the brain) or a blood clot in a blood vessel located in the brain |
| Syncope | Fainting spells |
| Tinnitus | Ringing in the ears |
